I got one of these merely so I could check intermediate rainfall totals
without having to go out & get wet.

I've noticed that it seems to under-read, especially for low rainfall
totals, and I had to change the clock, otherwise the daily totals reset
at midnight.

I've had one of those for a couple of months. I also get the feeling that
it under-reads but have had nothing to compare it with.

Fortunately I have a standard copper rain gauge for comparison.

It also does funny
things - it added last night's rain total (early hours of today) to it's
weekly total but it's day's total (today) remains at zero.

Yes, it has a tendency to such oddities.

Also, since it only tips in 1mm increments, it obviously won't record
anything less than that.

Never mind - I got a Davis Vantage Pro 2 a couple of days ago :-) I'll
leave the Maplins rain gauge running and compare the 2 rain readings when
we next get rain. Will post the results.

March will be the first full month for comparison, so I'll see how it
goes.
